高臭氧水平导致的橙色空气质量警报代码正在影响中南部和圣路易斯,敦促居民限制户外活动。 A Code Orange air quality alert due to high ozone levels is affecting the Mid-South and St. Louis, urging residents to limit outdoor activity.

由于臭氧含量升高,在南部部分地区,包括谢尔比、克里滕登和德索托州,以及纳什维尔大都会和大圣路易斯地区,都实施了橙色空气质量警报守则。 A Code Orange air quality alert is in effect across parts of the Mid-South, including Shelby, Crittenden, and DeSoto counties, as well as Metro Nashville and the Greater St. Louis area, due to elevated ozone levels. 高温、空气停滞以及来自车辆和工业的污染助长了臭氧的形成,对诸如哮喘、心脏病、儿童和老人等敏感群体构成健康风险。 High temperatures, stagnant air, and pollution from vehicles and industry contribute to ozone formation, posing health risks to sensitive groups such as those with asthma, heart conditions, children, and the elderly. 建议居民限制户外拉力,避免兜售车辆、拼车,不要使用汽油动力设备。 Residents are advised to limit outdoor exertion, avoid idling vehicles, carpool, and refrain from using gasoline-powered equipment. 预计警报将持续到星期四,预计到周末会有改进。 The alerts are expected to continue through Thursday, with improvements anticipated by late week.
